Definitions
- punch and die tooling for blanking or cutting a plurality of parts from a sheet metal workpiece with each stroke of the press and by positioning each punch at a slightly different elevation corresponding to the thickness of the sheet metal workpiece.
- the blanking of the parts is performed in sequence, but the holding of the workpiece is performed by one plate without any sequence.
- the present invention is directed to an improved method and apparatus for constructing and operating the tooling for a press for producing a plurality of cup-like articles with each stroke of the press and which provides for significantly increasing the operational speed of the press to obtain a higher production rate without overloading components of the press.
- a cupping press equipped with tooling constructed in accordance with the present invention is capable of obtaining more than a 50% decrease in the compressive forces or loading on the outer ram and this decrease permits the speed of the press to be increased from about 150 spm to about 250 spm without exceeding the load rating of the press.
- a cupping press is equipped with multiple stage tooling wherein each tooling stage includes a plurality of annular draw pads each opposing a corresponding annular blank and draw die, an annular cut edge die surrounding each of the draw pads and a corresponding die center punch within each of the draw pads.
- the tooling stages are constructed for sequentially engaging the sheet metal with a precise timing sequence which provides for sequentially blanking a series of circular blanks between the cut edge dies and the corresponding blank and draw dies during each stroke of the press, sequentially holding the blanks between the draw pads and the corresponding blank and draw dies, and then sequentially drawing the blanks into cups with the die center punches extending into the corresponding blank and draw dies.
- the tooling of an existing cupping press may be easily modified by installing a series of annular shims for some of the draw pads and the retainers for the cut edge dies and by lowering the retainers supporting some of the blank and draw dies.
- the present invention also provides for conveniently and quickly removing upper tooling components to simplify servicing of the tooling after an extended period of use.
- FIG. 1 is a general plan view of lower cup forming tooling constructed in accordance with the invention and with the stock plate removed;
- FIG. 2 is a fragmentary section of the upper and lower cup forming tooling in a double action press, and showing the multiple stages of the tooling as taken generally on the line 2--2 of FIG. 1;
- FIG. 3 is an enlarged fragmentary section of one of the tooling stages shown in FIG. 2;
- FIG. 4 is a fragmentary exploded view illustrating the assembly of upper tooling components shown in FIG. 3;
- FIGS. 5-7 are enlarged fragmentary sections of the tooling components shown in FIGS. 2 & 3 and illustrating the sequential blanking, holding and drawing operations in accordance with invention.
- FIG. 8 is a chart illustrating the relative positions of the multiple stage or stepped tooling components shown in and FIGS. 2 & 5-7.
- FIG. 1 illustrates a plan view of the lower or bottom tooling of a fourteen cup tooling system 15 which includes a lower die shoe 18 secured to a bed 20 (FIG. 2) of a double action mechanical press.
- the press also includes an inner ram 22 and an outer ram 24, with the inner ram 22 having a vertical stroke, for example, of about five inches and the outer ram 24 having a substantially shorter stroke, for example, about two inches.
- the lower die shoe 18 has a series of fourteen holes or pockets 26 which extend vertically or downwardly through the lower die shoe 18 to a cup discharge chamber 28.
- the pockets 26 are arranged in four stages (FIG. 1) with pockets 1, 2, 13 and 14 forming stage 1, pockets 3, 4, 11 and 12 forming stage 2, pockets 5, 6, 9 and 10 forming stage 3 and pockets 7 and 8 forming the center stage 4.
- the inner ram 22 (FIG. 2) supports an upper or inner die shoe 32.
- a series of vertical risers 34 are secured to the bottom surface of the inner die shoe 32 and extend downwardly in vertical alignment with the corresponding pockets 26.
- a die center punch 38 (FIG. 3) is secured to the lower end portion of each riser 34 by a center screw 39 and a precision locator pin 41, and each die center punch 38 carries a hardened outer wear sleeve 42.
- Each of the risers 34 and the corresponding die center punch 38 have a vertically extending air passage 44 which receives a supply of pressurized air at timed intervals for removing cups from the punch.
- the risers 34 and corresponding die center punches 38 are carried by and move vertically with the inner ram 22 through the attached inner die shoe 32.
- a cylindrical guide sleeve 46 (FIG. 3) surrounds each of the risers 34 and has an upper flange secured to an annular plate 48 which is mounted on an upper die shoe 52.
- the upper die shoe 52 is carried by the outer ram 24 through a series of peripherally spaced screws 54 (FIG. 2).
- a cylindrical liner 57 lines a bore within the upper die shoe 52 and cooperates with the sleeve 46 and plate 48 to define a fluid or air chamber 59 which receives the head portion of a piston 62.
- the head portion carries wear pads (not shown) within peripherally spaced holes 63 and is confined within the chamber 59 by an annular retainer 64 secured to the upper die shoe 52 by peripherally spaced screws 66 and a precision locator pin 67.
- a two section draw pad 70 is supported for vertical sliding movement within the annular retainer 64 below the piston 62, and the bottom surface of the draw pad 70 has a series of fine concentric grooves or recesses to form an irregular surface.
- the lower portion of the draw pad 70 is formed from a harder steel than the upper portion which engages the piston 62 and carries wear pads (not shown) within peripherally spaced holes 73.
- the draw pad 70 is retained within the annular retainer 64 by an annular cut edge retainer 74 secured to the retainer 64 by a series of peripherally spaced screws 77.
- the retainer 74 supports a hardened annular shearing die or cut edge 78 which surrounds the draw pad 70.
- a hardened flat spacer ring 82 is recessed within the upper portion of the cut edge retainer 74 and forms a lower limit of movement for the draw pad 70.
- each of the holes or pockets 26 within the lower die shoe 18 is vertically aligned with the corresponding die center punch 38 and is slightly larger in diameter.
- a two section annular blank and draw die 90 which is supported in a circular recess of an annular retainer 93 by a flat annular spacer 96.
- Each blank and draw die 90 is secured to its corresponding retainer 93 by a set of peripherally spaced screws 98, and another set of screws 101 secures each retainer 93 to the lower die shoe 18.
- a set of screws 102 secures the spacer 96 to the blank and draw die 90.
- Locating pins and bushings are also used to align each blank and draw die 90 and its retainer 93 precisely on the lower die shoe 18.
- the upper portion or section of the blank and draw die 90 consists of a hardened ring which is inserted and positively retained within the lower portion or section of the die 90.
- the die center punch 38, draw pad 70, surrounding cut edge retainer 74 and cut edge 78, piston 62 and piston retainer 64, which form part of the upper tooling on the upper die shoe 52, may be conveniently and quickly removed from the die shoe 52, simply by removing the screws 39, 66 and 77. Furthermore, these components may be removed for replacing components such as wear pads or piston sealing rings without further elevation of the upper die shoe 52 or without further disassembly of the upper tooling.
- a flat stock plate 110 forms part of the bottom or lower tooling and defines a circular opening or clearance hole 111 for receiving each of the blank and draw dies 90.
- the stock plate 110 is supported with its upper surface generally flush with the upper surface of the blank and draw dies 90 by a series of spring biased pistons 115 (FIG. 2) which are located within the lower die shoe 18 between and around the blank and draw dies 90, as shown in FIG. 1.
- the spring loaded pistons 115 biased the stock plate 110 to its elevated position (FIGS. 2 and 3) with a predetermined force, but permit the stock plate 110 to move downwardly by a fraction of an inch when the force is exceeded by the downward movement of the cut edges 78 and retainers 74.
- the multiple stage tooling described above in connection with FIGS. 1-4 operates to perform sequential blanking, holding and drawing operations with respect to sets of the holes or pockets 26. These sequential operations are performed by precisely positioning each stage of the blank and draw dies 90, the draw pads 70 and the die center punches 38 at predetermined elevations relative to the press bed 20.
- existing cupping tooling may be modified by grinding the bottom surfaces of some of the blank and draw die retainers 93 to lower the blank and draw dies, and by adding a set of shims to the upper tooling for each of the stages 2, 3 and 4.
- a flat annular shim 120 limits the downward movement of each draw pad 70 relative to its surrounding cut edge 78
- an annular flat shim 121 limits the downward movement of the corresponding air actuated piston 62 which presses downwardly with a predetermined pressure on the draw pad 70.
- Another annular flat shim 122 spaces or lowers each of some of the die center punches 38 with respect to its supporting riser 34 and precisely determines the elevation of the die center punch with respect to its surrounding draw pad 70.
- the blank and draw dies 90 for the holes of stages 1 and 2 are each lowered by 0.012 inch. This lowering is accomplished by grinding the bottom surfaces of the retainers 93 supporting the corresponding blank and draw dies 90.
- the shims 120 and 121 for the stage 2 pockets 3, 4, 11 and 12 have a thickness of 0.020 inch so that the pistons 62 for the pockets of stage 2 and the corresponding draw pads 70 are elevated by 0.020 inch above the pistons 62 and draw pads 70 for the stage 1 pockets 1, 2, 13 and 14.
- the die center shims 122 for the stage 2 pockets 3, 4, 11 and 12 have a thickness of 0.060 inch so that the die center punches 38 for these pockets are lowered by 0.060 inch relative to the die center punches for the stage 1 pockets.
- the shims 120 and 121 for the stage 3 pockets 5, 6, 9 and 10 have a thickness of 0.052 inch so that the pistons 62 and draw pads 70 for these pockets are elevated by 0.040 inch above the draw pads 70 for the stage 2 pockets.
- the die center punch shims 122 for the stage 3 pockets have a thickness of 0.116 inch so that the die center punches 38 for these pockets are 0.056 inch lower than the die center punches for the stage 2 pockets.
- the shims 120 and 121 for the stage 4 pockets 7 and 8 have thickness of 0.072 inch
- the die center punch shims 122 for these pockets have a thickness 0.198 inch so that the draw pads for these pockets are elevated by 0.020 inch above the draw pads 70 for the stage 3 pockets, and the die center punches 38 for the stage 4 pockets are 0.082 inch lower than the die center punches 38 for the stage 3 pockets.
- a sheet S of metal such as 0.011 inch thick aluminum, is fed between the upper tooling and lower tooling in the downward direction in FIG. 1.
- the downward movement of the outer ram 24 and the upper die shoe 52 causes the sheet S to be sequentially sheared or blanked between the annular cut edges 78 and the annular blank and draw dies 90 for the stages 1-4 for progressively forming the flat circular blanks B.
- the blanks B are sequentially clamped or held against the blank and draw dies 90 by the draw pads 70 for the stages 1-4 as a result of the shims 120 and 121 with increasing thickness.
- the downward movement of the inner ram 22 and inner die shoe 32 causes the die center punches 38 for the stages 1-4 to engage the blanks B sequentially and to draw the blanks sequentially into corresponding cups C.
- the increasing thickness of the shims 122 above the die center punches 38 for stages 1-4 results in the cups C being sequentially drawn in a reverse order, with the cups C for stage 4 being fully drawn prior to the cups for stage 3 being fully drawn and prior to the cups for stage 2 being fully drawn prior to the cups at stage 1.
- a mechanical cupping press equipped with tooling constructed in accordance with the present invention provides desirable features and advantages.
- the dynamic loading on the outer ram 24 is substantially reduced.
- the compressive load of 98 tons on the outer ram of a 150 ton press with eight pocket tooling operating at 250 spm is reduced to a compressive load of 48 tons with tooling constructed in accordance with the present invention.
- cup-like articles includes a plurality of any drawn sheet metal articles each of which has a bottom wall integrally connected to an upwardly projecting annular wall.
